Paddling
Paddling Index methodology v1.0 · calculated 2026-09-25Sylvan Lake has a mostly natural, lightly developed setting, generally sheltered geometry, some nearby classified roads.
Why this score?5 components
Included in the index
| Component | Rating | Points of weight | Measurement |
|---|---|---|---|
| Natural setting | Very Good | 24.2 of 35 | 73% natural land cover within 150 m of shore (57% forest, 15% wetland; 14% developed) |
| Geometric wind exposure | Very Good | 19.3 of 29 | mean fetch 952 m · 14% of sampled water within 500 m of shelter · generally short fetch |
| Motor & speed rules | Not modeled | — | Minnesota’s lake-by-lake motor, speed and no-wake rules are mostly county and city ordinances, not map data, so they are not part of the Minnesota index. Check local signage and ordinances before going out. |
| Public access | Good | 12.3 of 18 | 1 DNR public access site · shoreline access |
| Road isolation | Good | 9.4 of 18 | some nearby classified roads · 2 MnDOT-classified segments within 1.2 km, peak 753 vehicles/day |
Additional paddling considerations
These describe the lake but are not part of the v1 Paddling Index and do not change the number above.
- Wake sensitivity
- Low — wide enough that wakes disperse over most of the lake
- Aquatic vegetation
- Low — approximately 2% mapped coverage · NAIP aerial imagery (NDVI)
- Observed motorized activity
- Unknown — No lake-level measurement of boat traffic is available. Legal permission to operate motors is not evidence of use.
- Wildlife habitat potential
- Moderate — 57% forest and 15% wetland cover within 150 m of shore

- Faucet SnailListed in 2025 because this water is connected to Crow Wing River. The species has not necessarily been found in this lake.

What does the infested waters list mean?
The Minnesota DNR lists a lake, river, pond or wetland as infested when it contains an aquatic invasive species that could spread to other waters, or when it is connected to a water where one is present. Activities such as bait harvest and water use are managed differently on infested waters. Check the current list before moving water, bait or equipment.
